PHP mailers are, as the name suggests, tools intended to send e-mails using php commands. CMSs like WordPress, Joomla or Magento have builtin functions to send e-mails. However, malware creators have their own specially crafted scripts to send messages. Such scripts can be used for sending spam, phishing e-mails, flooding mailboxes or stealing and sending sensitive data back to the malware creators.
